Gym Locker Room

So I love working out, I go to the gym 5 or 6 days a week. I keep to myself and get my work done and then go about my day. I've always considered myself straight but lately I've found myself being turned on by cock and by the thought of sucking cock. As fate would have it I was at the gym at a different time than usual, I had finished my workout and was in the locker room about to change clothes. A man comes out of the shower room naked, no towel, nothing. When he sees me he apologizes and said he would've put on towel had he known I was there. I assured him it was all good and tried to go about my business but damn.... that cock was beautiful.... and he caught me checking it out... he smiled said nothing but I knew I had been caught. I grabbed my towel and practically ran to the showers. I stroked my cock in the shower and shot everywhere. When I got back to the locker room he was gone.... I think I missed an opportunity........
